FNC116 – ESTR / Floating Point to Character String Conversion
Outline
This instruction converts binary floating point data into a character string (ASCII codes) having a specified
number of digits.
On the other hand, STR (FNC200) instruction converts binary data into a character string (ASCII codes).
→
For a character string, refer to Section 5.3.
→
For handling of floating point, refer to Subsection 5.1.3.
→
For STR (FNC200) instruction, refer to Section 26.1.

Explanation of function and operation
1. 32-bit operation (DESTR and DESTRP)
The contents (binary floating point data) of [
+1,
] are converted into a character string according
to the contents specified by
,
+1 and
+2, and then stored to devices
and later. A real
number can be directly specified as
.
• The data after conversion varies depending on the display specification stored in
.
